COMMISSIONING THE CHARGER
Rechargeable batteries with more than 1 cell in lithium technology usually
have a balancer connection. This connection is used for monitoring of every
single cell by a charger or balancer and protecting it from over-charging. If the
rechargeable battery to be charged has such a balancer connection, this
connection is to be connected to the charger every time the battery is charged.
The charger has an integrated balancer. Since there are different balancer
plugs, a special plug version was dispensed with a universal connection (4)
was provided. For this, observe the following notes in this chapter.
For charging, observe the warning notes of the rechargeable battery
manufacturer regarding maximum charging current and maximum permissible
temperature of the rechargeable battery.
• Connect the charger to a stabilised direct current (11 – 15 V/DC, e.g. a car battery) in the
right polarity with the connection lines (1). The red cable must be connected to the plus,
the black to the minus pole of the voltage source. The device now performs a self-test.
For a short moment, the display (2) shows all segments.
• After a self-test, the display automatically changes back and forth between volt and
ampere display. If no rechargeable battery is connected yet, the volt display 0.00V is
shown. The ampere display shows a value between 0.1 and 3.5 A, depending on the
position of the rotary control for the charging current (7).
• Now connect the rechargeable battery to be charged to the charging output sockets of
the charger (3) with a suitable charging cable in the right polarity. The plus pole of the
rechargeable battery must be connected to the red socket and the minus pole of the
rechargeable battery to black charging output.
• If the rechargeable battery to be charged has a balancer connection, this connection
must be connected to the balancer socket of the charger (4) every time the battery is
charged. The minus pole of the rechargeable battery's balancer connection is to be
connected to the terminal pin (5) marked as minus pole.
• Select the right lithium battery type with the battery type button (6). Attention! If the
wrong battery type is selected, all charging parameters will no longer match the battery
type. This poses a danger of destroying the rechargeable battery. There also is a danger
of fire and explosion!
• When the charging current is displayed, set the desired charging current with the
charging current rotary control (7). For this, observe the instructions of the rechargeable
battery manufacturer. Attention! If the maximum permissible charging currents of the
manufacturer are not observed, this poses a danger of destroying the rechargeable
battery. There also is a danger of fire and explosion!
• After verifying all settings and connections, you can start the charging procedure by
pressing the start/stop button (8). Note: The charging process can be interrupted at any
time by pressing the start-stop button again.
• While charging, the display (2) automatically switches to show the following parameters:
Volt = current charging voltage, Ampere = current charging current, milliampere hours =
the energy and time with which the battery is currently charged = current charging time.
• While charging and while the rechargeable battery's balancer cable is connected, the
LED displays for the balancer (9) are also lit.
If the LEDs are always lit, the respective call is currently being "balanced", i.e.
adapted to the other cells by a controlled discharging current. If the LEDs only light
up sporadically or not at all, the cells are "balanced", i.e. all cells have the same
voltage level.
• If there are any errors in the charger and/or rechargeable battery, the device shows
these errors in the display and a warning signal sounds. It is possible that the charging
process cannot be started or that a charging processes is uninterrupted. For this,
observe the notes in the following chapter "Error messages".
• The charger will automatically end the charging process when the rechargeable battery
is charged completely and "balanced". When the rechargeable battery is full, the display
indicates "FULL" and a signal sounds. Now unplug the rechargeable battery and remove
the terminal clamps (1) from the supply voltage.

ERROR MESSAGES ON THE DISPLAY

If the charger recognises any errors, the display shows the respective error code and a
warning signal sounds. The following error messages can appear:
Err1: Interruption in the charging cable of rechargeable battery.
Err2: The high current charging connection (3) or balancer connection (4) was
disconnected during charging, or the connection is loose.
Err3: The input voltage at the terminals (1) is too low (below 11 V).
DISPOSAL
a) Product
Electronic devices are recyclable waste and must not be disposed of in the
household waste!
At the end of its service life, dispose of the product according to the relevant
statutory regulations.
b) Batteries and Rechargeable Batteries
You as the end user are required by law (Battery Ordinance) to return all used batteries/
rechargeable batteries. Disposing of them in the household waste is prohibited!
Batteries/rechargeable batteries that include hazardous substances are

labelled with these icons to indicate that disposal in domestic waste is
forbidden. The descriptions for the respective heavy metal are: Cd=cadmium,
Hg=mercury, Pb=lead (the designation is written on the rechargeable battery

e.g. under the rubbish can symbols depicted at the left).
You can return used batteries/rechargeable batteries free of charge at the
official collection points of your community, in our stores, or wherever
batteries/rechargeable batteries are sold!
You thus fulfil your statutory obligations and contribute to the protection of the
environment.
